Firefighters in Brazil have resumed their search for hundreds of people missing in the wake of a massive dam collapse. The dam burst at Vale’s Corrego do Feijao mine in southeastern Brazil unleashed a torrent of mud on Friday, burying the mining facilities and nearby homes in the town of Brumadinho. Nearly 300 people are still missing, with the list of those unaccounted for being constantly updated, Flavio Godinho, a spokesman for the Minas Gerais civil defense agency, said.
